Instrument Type

X-RAY DIFFRACTION - XRD X-ray powder diffractometer

Rigaku MiniFlex


Typical Use:

Routine identification of crystalline materials; processing software includes Jade and MacDiff

Conditions for Use:

Submitted samples will be analyzed on a contract basis (i.e. lab personnel will do the work).
Visitors are invited to work in the lab to work with lab personnel.
Visitors are invited to work in the lab to design and do the work yourself.

User Fees:

Charges vary with project, but we generally charge /hr instrument time (academic rate) with a 1 hour minimum. Additional charges for operator assistance, unusual sample prep, etc. may be applied.

Instrument Priorities:

Class exercises, student research, and faculty research have priority use, but the instrument is not heavily used and is likely to be available when needed.

Remote Use:


Sample Preparation:

Prepared powdered samples are preferred, and can be sent to J B Murowchick with advance notice by any available carrier. Please provide as much information about the sample as possible. Make arrangements before sending samples.

Standard Collections/Lab Blanks:

We calibrate the instrument using a powdered Si standard that came with the instrument (NOT NIST standard reference material).


Data acquisition is by Rigaku software. Pattern processing is done with Jade (MDI) for searching the PDF file, smoothing, peak measurements, some quantitative analysis (RIR method), and for conversion to an ASCII file.
The ASCII file can then be opened in MacDiff for further identification of phases, peak measurements, and export to graphics programs for making figures or slides.

Educational Use:

Class demonstrations are available for undergraduates.
Class demonstrations are available for K-12.
Undergraduate student research projects are invited.
Graduate student research projects are invited.
None currently prepared, but I'm open to collaborating on such projects.

Support provided by:

Operation funded by department.
